Disclaimer: I'm pretty sure the terminology I'm using is mistaken, please advise what terms are more suitable/correct.
I have two questions, both about the same situation, right at the bottom.
The most simplified view of my network is as follows:-
Modem (fibre-optic) -> OfficeRouter -> PublicRouter
That is to say, the LAN cable from the modem goes to the WAN slot in my OfficeRouter, and the PublicRouter is connected to one of the LAN slots in my OfficeRouter.
Both OfficeRouter and PublicRouter broadcast their own SSIDs, called
publicssid. Additionally, up to a dozen PCs are connected to OfficeRouter via LAN (through switches).
Physical placement constraints mean I cannot change the relative ordering of my routers.
Current networking setup
Each router runs its own DHCP service, so all clients connecting to OfficeRouter (via
privatessid or LAN) get something on 192.168.0.* and all clients connecting via PublicRouter get something on 192.168.1.*
How can I 'mask' or prevent access to machines connected to OfficeRouter from machines connected to PublicRouter? One of the byproducts of my unfortunate physical arrangement of routers is that all the office machines are directly accessible by anyone connected to
Is it possible to handle more than 255 connections to
publicssid? Do I just have to change the subnet mask for that to work, or is there something I'm missing. The routers in question are fairly basic, are there practical considerations for handling that many connections at once?
